Heretofore this tension has been se- In order partlyto overcome the bad effects cured by the application of a frictionalbinder. of producing tension on the wire entirely by to the reelcontaining the wire which is to be means of the nut on the reel the wirehas somewound into the cylinder. This reel turns on times been drawnaround a wheel placed out 10c side of the reel and between the latterand the cylinder. In this case the wire made an entire lap about suchwheel, and the wheel was either stationary, the wire slipping around it,or it revolved under friction produced similarly to the friction on thereel. This device only partly overcame the difficulties described andintroduced another diflicultyviz., that as the wire both passed on andoff of the intermediate wheel at the same point the wire crossed itselfat that point, producing a rubbing action which was detrimental to thepoints of the teeth of the wire. By the use of this intermediate wheelthe friction on the reel could be made less tight, but could not bewholly dispensed with.

Our improved apparatus entirely removes the objections specified, andthe wire as it passes from the reel is under only so much tension as isnecessary to revolve the reel to allow the wire to pass off, thefriction being retained on the reel with only sufficient force to givesteadiness to the motion of the latter.

As constructed by us our apparatus consists, essentially, of two wheelsor rolls between which the wire passes, and by which it is nipped, sothat it cannot slip between them, the necessary tension being producedby applying friction to one or both of the wheels or rolls.

In the accompanying drawings representing our invention, G is the bottomroller, in which are cut annular grooves of different sizes to receivethe various sizes of wire, as may be seen atg g &c. These grooves arenot sufficiently deep to receive the entire body of the wire, but leavea part of the latter above the surface of the roll, so that it can bepressed upon by the upper roller, the wire resting on its flat or side,and not on its edge, in the groove it occupies.

II is the upper roller, which is roughened by a series of ridges, h,raised on its surface, such ridges being arranged parallel to the axisof the roll. This roll is preferably of steel, and the ridges producedby a filecutters chisel, after which the surface of the roll is hardenedto give it greater durability. This roll by its roughness gets a goodhold on the wire and wholly prevents it from slipping between the rolls.

The roll G is mounted 011 the shaft I,which shaft has suitable bearingsin the two standards .I J. The shaft I may turn in its bearings, theroll G being attached to the shaft, or, as shown in the drawings, theshaft may be stationary, and the roll turn loosely on it; but in anycase provision must be made for the lateral adjustment of the roll Gthat the wire may be guided vertically downward over the edges of thecylinder being clothed. This adjustment is required to suit the variousdiameters of cylinders. In the drawings the roll G is held between thetwo stationary collars G G, one on either side of it, and by unscrewingand slipping the collars on the shaft the necessary adjustment of theroll is ob tained.

The roll If is mounted through the medium of the shaft H in a frame orcradle, K,whieh cradle is pivoted on the shaft 1, the latter havingbearings in the standards J J. The cradle K, where it rests on the shaftI, is held from lateral movement by the two collars K K, one on eitherside of it, and by unscrewing these collars and sliding them on theshaftI the cradle may be adjusted sidewise to any desired position, so as tokeep the roll II always over and opposite to the roll G wherever thelatter may happen to be placed.

One side of the cradle K has an extension or arm, K, formed with notches7. to receive a suspended weight, M. By moving this weight along the armK and by using various sized weights any degree of pressure desired maybe applied to the roll II where itimpinges on the wire that is passingbetween the rolls. For coarser wires a heavy pressure is required, butlighter and more delicate wires require less pressure. The object ofthis pressure is to bind the wire so it cannot slip between the rolls.

The roll H is securely fastened to the shaft H, so that when the rollturns the shaft must turn also. One end of the shaft 11., at II,projects beyond the side of the cradle K, and on this projecting end ofthe shaft is placed the ,friction clamp N. This friction-clamp consistsof two parts, a a fastened together by bolts n a, with a piece ofleather between the parts and encircling the shaft. By screwing theparts of this clamp together with greater or less tightness anydesirable degree of friction may be obtained. It is this friction whichby opposing, but not wholly preventing, the rotary motion of the rollI-I gives the tension to the wire, which tension is varied as thefriction is.

The friction-clamp N might be a part of or rigidly attached to thecradle K, but we prefer to make it with a projecting arm on'one part ofthe clamp, the end of which arm rests against one end of a coiled wirecompressionspring I the other end of the spring being attached to orresting againsta similar projection on the cradle K. By interposing thespring between the clamp and the cradle any irregularities in theturning of the roll G, caused by unevenness of the wire or dirt or otherforeign substance 011 the wire or by other cause, is equalized and amore uniform average tension placed upon the wire. The collar N issimply to keep the clamp N from slipping off the end of the shaft.

0 is a guide for directing the wire accurately between the rolls G andH.

In the drawings the standardsJ J are shown attached to the carriage ofthe lathe, the ways YY of which are shown in cross-sections of thedrawings, and the whole apparatus moves with the carriage X, which isshown mounted upon said ways and moving thereon in the ordinary manner,and, the calking-tool being properly adjusted, the wire is always guidedexactly into the groove ofthe cylinder Q wherever the carriage mayhappen to be placed; but, while we prefer to use our apparatus on thecarriage as described it could be attached immovably to the end or otherpart of the lathe or otherwise supported from a post, the ceiling, orany appropriate means of support, and the wire led from the apparatusover a guidewhcel similar to that heretofore used, as 'alreadysuggested.

Our apparatus may be variously modified and several well-knownmechanical appliances used to carry the principle of our invention intoeffect. For instance, instead of the weight M, springs might be employedto put pressure on the. roll H, and, instead of the cradle K beingpivoted as described, the bearings of the shaft H might slide invertical ways and the pressure obtained by weights or springs applied tosuch bearings. So, too, the coiledwire spring on the clamp N might be anextension instead of a compression spring and placed on theother side ofthe lever, or the spring could be a fiat spring or a piece of rubher.and, in place of the two rolls running together and nipping the wire,flat or curved slides or shoes might be used, between which the wirecould be drawn to produce the required friction; or one roll only mightbe used and opposed to a stationary non-revolving wheel, slide, or shoe.

What we desire to secure by Letters'Patent 1. The rolls G H, incombination with the shaft H, cradle K, weight M, and clamp N, for thepurpose of producing tension on the wire, for the purpose described.

2. The combination of the two rolls G and H, shaft H, cradle K, weightM, clamp N, and spring P, substantially as shown and described.

3. The combination of the standards J J, rolls G H, cradle K, weight M,clamp N, spring P, and shafts I, H, and l, constructed and arrangedsubstantially as and for the purpose described.

4'. In combination with the carriage of a lathe, the standards J J,rolls G H, cradle K, shafts I, I, and H, weight M, and clamp N, allarranged and constructed substantially as described, for purposes setforth.

5. The laterally-adjustable roll G, having grooves of difi'erent widthsfor various sizes of wire, in combination with a roll or presser forproducing friction or nipping the wire, substantially as shown anddescribed.

In testimony that we claim the foregoing we have hereunto set our handsthis 8th day of March, 1886.
